Calc: The table containing fields that 'evaluate' several parameters.
Equation: The table containing the equations: 1 field for each parameter and within year field several records containing however many alternative equations for calculating that parameter.
I would like to keep all the equations within a single table. Is the only way of doing this to put them all in, duplicate the table, then change the name of the duplicate to make it a different table? ie. I can't use TO's for different parameters because the relationship would interfere with choosing from different parameters on different record?
